Typescript Design Patterns (Object-oriented programming) (Skillshare)

There are many possible solutions but they probably won't be as flexible as using a decorator pattern.

Try applying the learned design patterns into a fun project or exercise. For example: choose a pattern to build a cash register for a coffee shop. Customers can order any coffee from the menu and customize their order depending on taste. They can for instance choose to add sugar or milk. Or maybe they want a special topping or flavor added to their coffee. After entering all the options, your application should return the total price of the custom coffee.
